Patented May 24, 1938 UNITED STATES PATENT OFFICE 1 Claim.

One object of this invention is the provision of a novel physical exercising device, simple in construction and operation, and inexpensive in cost oi manufacture.

Another object of the invention is the provision of such a device which is formed of elastic material provided with 'handle members adapted to be grasped in the hands, the same being stretched preferably in rythmic manner in order to develop the muscles of the arms.

A further object of the invention is the prof vision of detachable handle members on such a device.

The above and other objects will become apparent in the description below, in which charcters of reference refer to lkemamed parts in the drawing.

Referring briefly to the drawing, Figure 1 is a view illustrating the manner of using the device as an exerciser.

Figure 2 is a view illustrating the details of the device, showing one of the handle members in open position.

Figure 3 is a view at right angles to Figure 2.

Figure 4 is an enlarged fragmentary side View of one of the handle members.

Figure 5 is a cross-sectional view taken on the line 5-5 of Figure 2.

Figure 6 is a cross-sectional view taken on the line 6-6 of Figure 2.

Figure '7 is a fragmentary view, partly in crosssection, showing a modied form of handle member.

Referring in detail to the drawing, the numeral l!! represents an endless band or the like of relatively stout flexible material such as rubber, circular in cross-section.

At oppositely spaced apart points on the band IS, handle members l l are mounted. Each member I I comprises two semi-cyclindrical halves I2 and I3 mutually hinged together at I4. On the inner surfaces of the half sections I2 and I3, raised and more or less pointed bosses I5 are provided.

Along the edge of each of the sections I2 and i 3 opposite the edge having the hinge I4 thereon, spaced apart tubular sleeves IB and Il are provided, respectively. The spaces between these sleeves on each section are equal to the lengths of the sleeves, and the sleeves I8 are staggered with respect to the sleeves Il, so that when the two sections are closed about the band I0, the sleeves of one section register in the spaces between the sleeves of the other section, as shown in Figure 4. Wnen in this closed position, the openings in ail of the sleeves I6 and I1 are in alignment, and a pin i8 is passed therethrough to lock the sections together. This pin has a head i5 at one end, and either the pin or the in- 10 ner walls of the sleeves i6 and Il may be provided with a coating of some material such as rubber, so that the pin will be retained releasably therein.

When the handle members are mounted onA the 1 band l, the bosses i5 prick the rubber of the band and prevent slipping of the handles thereon. When it is desired to replace the band I0, the handies are simply removed in an obvious manner and remounted on the new band. 20

In the modified form of handle member shown in Figure 7, the cylindrical outside shell 2l) of the handle is formed of hard or relatively hard rubber. Securely xed in this shell 20 is a metal lining 2l rounded in cross-section from the midpoint of the handle toward each end. The band IG passes through this handle and lies in contact with the rounded surface of the lining. The rub-; ber shell gives the handle a good soft gripping surface, and the metal lining gives the handle strength and rigidity. In this form the handle may be readily k:slid around the band, and the curvature of the lining 2l reduces the strain on the band at the point where it enters and the point where it leaves the handle.

Obviously, modifications in form and structure may be made without departing from the spirit oi the invention.

I claim:

An exercising device comprising an endless rubber band normally oblong in outline, handle members each comprising a pair` of mutually hinged semicylindrical sections adapted to be closed about the short sides of said band to enclose said band therebetween, means for locking said sections in said closed position, and means for locking said band in said closed handle member sections.
